<p><P>PROBLEM TO BE SOLVED: To provide a fluid injection head manufacturing method and a fluid injection device manufacturing method for actualizing a uniform discharge amount of fluid. <P>SOLUTION: The manufacturing method is provided for a fluid injection head which consists of a flow path unit having a plurality of nozzle openings for injecting fluid and pressure chambers communicated with the nozzle openings, respectively, a piezoelectric unit having a piezoelectric element for giving vibration to a vibration plate for the flow path unit and a fixing plate for fixing the piezoelectric element, and a head case having a storage chamber for storing the piezoelectric unit. It comprises a storing step of storing the piezoelectric unit in the storage chamber so that the piezoelectric element abuts on the vibration plate, a thrusting step of thrusting the piezoelectric unit in the storing direction so that part of the piezoelectric unit abuts on the side wall face of the storage chamber, and a fixing step of bonding and fixing the piezoelectric element to the vibration plate and the fixing plate to the head case in the state that the piezoelectric unit abuts on the vibration plate and the side wall face. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
